4 Claims.

This invention relates to loading machines, and has special reference toa manure loader.

One important object of the invention is to provide a novel device ofthis character which may be attached beneath an ordinary farm tractorand operated from the mechanism of such tractor.

' A second important object of the invention is to provide a device ofthis character wherein the attachment to the tractor is such that thedevice may be raised or lowered, as desired.

A third important object of the invention is to provide a novelarrangement of parts in a 'device of this kind, whereby manure may bechopped up into small portions for the purpose of more readily loadingand conveying the same.

A fourth important object of the invention is to provide a novelarrangement of means for pitching chopped manure onto a conveyor.

A fifth important object of the invention is to provide means at theends of the conveyor forming a part of this invention such that thematerial will be delivered on top of the conveyor and may be deflecteddownwardly at the delivery end of such conveyor.

With the foregoing and other objects in View, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part, of this application wherein likecharacters denote corresponding parts in the several views, and inwhich:

In the embodiment of the invention as shown in the present drawings,there is provided a conveyor frame having a bottom H], a rear side wallll projecting upwardly from the bottom, and a correspondingly arrangedfront side wall i2. These side walls have outwardly flaring upperportions I3. Attached to the wall H is a frame plate having a portion I4which extends along the wall II and projects beyond the materialreceiving end thereof. The plate 14 is also provided with a portion l5which extends from the outer end of the portion I4 at an angle theretoso that the portion I5 is inclined forwardly from the portion I4. Whenin use, the portion l4 extends underneath the body of the tractor T andthe portion l5 extends from the left side of the tractor. Adjacent theangle between the portions l4 and [5, the portion l4 carries a verticalsleeve 16, and on each of the-walls l l and I2 adjacent the tractor sidethere is provided a vertical sleeve 11. Rods 18 project up from thesleeves I6 and [1, these sleeves being slidable on the rods, and therods have flattened upper ends 19 which are secured to the tractor bymeans of bolts 20. With this arrangement, the device is verticallymovable with respect to the tractor body.

In order to provide for vertically adjusting the device, a yoke 2| hasdepending arms 22 which are secured to the front wall I 2 and the plateportion M by bolts 23, as seen in Fig. 4. On the plate portion 15 ismounted a bearing lug 24 wherein is carried a pin 25 having on one end aforwardly extending link 25. Bearings 21 are provided for boltingbeneath the body of the tractor T and in these bearings is journalled arock shaft 28 on one end of which is fixed a rock lever 29 having thelink 26 pivoted thereto. At the other end of the shaft 28 is a rocklever 30 which has its forward end pivoted to the upper end of a link 3|and the lower end of the link 3| is connected to a bracket 32 fixed onthe yoke 2|. The shaft 28 also has fixed thereon one end of an operatinglever 33 which works beneath a quadrant 34 fixed on the side of thetractor T, and the lever 33 has an operating handle 35 and a latch 36for engaging in an appropriate notch of the quadrant 34. By manipulatingthe operating lever, it will be seen from Fig. 4 that the entire movableportion of the loader may be raised and lowered. Suitable bracing 31 maybe used to connect the conveyor sides to a link 38 pivoted to a bracket39 on the side of the tractor T. This bracing will prevent rocking ofthe conveyor.

At the inner end of the conveyor is a shaft 45 whereon is fixed a roller4| and a similar roller 42 is carried by a shaft 43 at the outer end ofthe conveyor. Around the rollers 42 and 4| is trained a conveyor belt 44having flights 45. Fixed to the sides of the tractor is a supportingyoke 45 carrying a bearing 41 wherein is journalled a shaft 48 whichextends longitudinally of the tractor. The shaft 48 comprises telescopicsections 49 connected by a universal joint 50 and on the rear section 49is fixed a sprocket 5|, around which is trained a sprocket chain 52which runs over a sprocket 53 fixed on the drive shaft 54 of thetractor, as shown in Fi 3. Thus the shaft 48 is driven from the tractor.The forward end of the shaft 48 is journalled in the plate [4 andcarries a sprocket 55, around which is trained a chain 56 which runsover a sprocket 5! fixed upon the shaft 4!} and thereby drives theconveyor. On the forward side of the plate I4 is a pitching wheel,indicated in general at 58, this wheel being fixed on the forward end ofthe shaft 48. The wheel 58 consists of a disk 59 having on its frontface a series of regularly disposed angle bars 50, each having one legresting on the disk 59 and its other leg projecting forwardly from thedisk. These bars are held on the disk as by rivets 6| orany othersuitable means. It will now be observed that when the shaft 48 rotates,the pitching wheel 58 will also rotate.

Carried by the plate portion I5 is an outwardly extending bracket 62having adjacent its outer end a pair of alined bearings 63 wherein isjournalled a shaft 64. On the rear end of the shaft 64 is a sprocket 55which is connected by a chain 66 with a sprocket Bl fixed on the shaft48. Can A ried by the plate portion I5 is a bearing boss 68 wherethroughextends a shaft 69 having a cutting or chopping wheel HI fixed on itsforward end in front of the plate l5. The cutting or chopping wheel I0is provided with an undulated and sharpened edge H. On the rear of theshaft 59 is fixed a bevel gear 12 which meshes with a bevel gear 13carried by the forward end of the shaft 64. By this means, rotation ofthe shaft 48 drives the shaft 64 and through the medium of the bevelgears effects driving of the chopping wheel 70.

A guide or guard member 14 is provided at the inner end of the conveyorproper and has a forwardly extending blade 15. Also a deflector member16 is pivoted on the shaft 43 and has a cover portion 11 which may bepositioned at any desired angle so as to deflect material passing oifthe conveyor downwardly.

In the operation of the device, the tractor is driven through the yardor other place at which the manure has been collected and as the tractormoves forwardly, the chopping wheel will rotate and chop the materialinto portions of such size as to be readily handled by the pitchingwheel. At the same time, the inclined position of the chopping wheel issuch that the material chopped will pass inwardly into the path of thepitching wheel. As this chopped material is reached by the pitchingwheel, it is picked up and tossed onto the lower end of the conveyorfrom whence it is conveyed to the upper end for delivery to a cart orother receptacle moving along with the tractor. It i of course obviousthat the operating lever will be used to set the height of the device ata proper point to effect the best disposition of the material to beloaded.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

It is obvious that changes may be made in the form and construction ofthe invention without departing from the material principles thereof. Itis therefore not desired to confine the invention to the exact formherein shown and described, but it is desired to include all such asproperly come within the scope of the appended claims.
